Fantasy is the root of all suffering. For example, fantasizing about oneself achieving promotion and wealth, fantasizing that one’s children can attend 985/211 universities, fantasizing about living in a luxurious mansion, driving a luxury car, marrying Her Highness the Eldest Princess, and then living to 150 years old. All of this is merely the carrot hanging in front of the donkey. Only when you completely abandon these fantasies can you live in the present and achieve true happiness.
